About 20 years ago I was going through a rough divorce, I decided to seek the help of a local therapist, during our sessions he began to tell me about a group he was creating. He had assembled a group of 10 men, various ages and backgrounds. His intent was to build and establish a Men's Group. I was curious so I agreed to check it out. For one year we met at the therapists office once a week . He would create different topics for meetings, some experiential, some not . He educated us on how a meeting should be structured, order maintained, creating a safe container, Etc...After one year we went off on our own without the support of the therapist. It has been 20 years now. About half including myself are original members, for various reasons , deaths, moving, new members have joined, the optimum number is about 10, it's what works for us...
